Two-pack black cartridges for HP 21 printers

This pack contains two refilled Dataproducts cartridges that replace the HP 21 black ink model. They are built for owners of compatible Deskjet, Officejet and PSC printers who want a lower-cost supply of black ink. The cartridges arrive new and ready to install.

Sustained printing with gauge warnings

Each cartridge is rated for approximately 10500 pages at five percent coverage. Because the ink gauge cannot be reset on remanufactured units, the printer will display a low-ink or previously-used warning during long print runs. Clicking OK or Continue on the prompt allows printing to proceed without interruption.

Standard thermal and power profile

The cartridges draw the same power and produce the same heat as the original HP 21 design during normal printing. No extra cooling or power consideration is required beyond what the host printer already provides. Acoustic output is unchanged from the stock cartridge.
